    Fix Status-Line in HTTP response

    There is a strict rule about constructing status line for HTTP:
    '...Status-Line, consisting of the protocol version followed by a
    numeric status code and its associated textual phrase, with each
    element separated by SP characters'
    (http://www.faqs.org/rfcs/rfc2616.html)

    This patch ensures an associated textual phrase for a status code
    is always written in the HTTP response.
